拟正常算子的谱及其连续性

The Spectra and Their Continuity for Quasinormal Operators

本文研究拟正常算子、纯拟正常算子的谱的精密结构和谱的各部分的连续性及其应用,所得到的某些结论发展了[1]的有关结果。

In this article, we discuss the fine structure of the spectra of quasinormal and pure quasinormal operators and the continuity of those spectra and give certain example of application. The conclusions obtained by us develop the related results of [1].
